WINDOW-CLEANER.

Specification of Letters Patent.

Patented Feb. 25, 1919.

. Application filed June 24, 1918. Serial No. 241,496.

To all whom it may concern:

Be it known that I, TOKIOHI KATO, a subject of the Emperor of Japan, residlng' at Tacoma, in the county ofPierce and State of Washington, have invented certain new and useful Improvements in Window-Cleaners, of which the following is a specificatlon.

This inventionrelates to window cleaning devices and is designed more especially for cleaning the front window glass of a loco-' motive or street car to enable the en neer or motor man to clearly see the track 1n advan ce of the car. I

The invention consists in the .novel constructiomhdaptation and combination of devices as will be hereinafter described and claimed.

In the accompanying'draw1ngs,

Figure 1' is a perspective View of a window equipped with a cleaner embodying my invention, said view being taken from the rearside. Fig. 2 an elevational view of; the

same from the rear or inside. Figs. 3 and 4 are sectional views through 33 and 4=4 of v Fig; 1. Referring to said drawings, the numeral 5 designates a pane of window glass of a sash 6'provided in a frame having side and head.

casing members 7 and 8. 9- represent upright pipes positioned in front of the win- .dow, and at oppositesides'of the sash. Said pipes have thelr upper and lower ends socketed in cup elements 10 of brackets 11 which are rigidly secured tothe casing members 7. Movable vertically in said pipes are cylindrical blocks such as 12, which are urged upwardly in the respective pipes by means of helical springs 13. Formed integral with, or rigidlysecured to, each ofsaid blocks is an arm 14 extending through slots, as 15, of

the ipes and also through slots 16 provided in t e casing members 7.

Secured to the ends of said arms and inside of the car is a horizontal handle bar 17. Outtally disposed blade 21 having connected thereto'a strip'22, of rubber, felt, or.other. material, suitable for cleaning the window pane 5.

v Springs 23, coiled about-the rod 19serve to yleldingly hold the strip 22 1n uxtapos 1- tion with the-outer or front surface of said pane. 24 represent deflectors secured to the window sashadjacent to its top and are each provided :with a resilient tongue 25 disposed in inclined relations with the plane of the window pane so as to engage studs 26 protruding. from the ends of the blade 21 to swerve the latter with the strip 22 outwardly when the blade approaches the upper end of its travel. When the studs 26 ascend above the tongues 25, the springs 23 assert themselves to return the strip 22 intocontact with the Window pane.

28 represents a hood secured to the casing member 8 and serves as a receptacle in which said blade and strip are housed and pr0- said devices to its idle position above the.

window pane. In such upward movement of the cleanlng devices, the tongues 25 cooperate w1th studs 26 to ward the strip from .the glass for the-purpose of passing over .any accumulation of dirt or moisture which may have been carriedup with the strip,

such dirt or moisture being carried in'the next downward movement of thestrip.

The invention is of simple and inexpensive construction and is efficient in operation.

What I claim, is-- 1. The combination in a window cleaning device, of a vertically movable rod, a cleaning strip pivotally connectedto said rod, a spring tending to retain said device in operative relation with the outside of the window pane, springs connected with both ends of said rod for yieldingly retainingsaid strip in its uppermost position, arms operatively connected to'the ends of said rod and extending through slots provided in the casing members, and a handle bar connected to said arms for effecting the downward movements of the. strip from the inside of the window.

. 2. The combination in-a window cleaning device, of a horizontal rod at the outside of the window, a cleaning strip carried b said rod, and engaging the outside of the window pane, slotted pipes secured to the window frame at opposite sides of the sash thereof,

blocks provided in the respective pipes, arms extending from said blocks through the respective pipe slots and through slots provided in the casing member to the inside of ing device, of a vertically movable windowpane cleaning strip, springs serving to press said device against the outside of said pane, and means to efiect the vertical movements the window, said arms being provided With Of the cleaner, of means to cause said strip branches to which the aforesaid rodis secured, springs provided in the pipes and acting through the medium of. said blocks to yieldingly retain the cleaning strip at its uppermost position, and a handle bar connected to said arms for effecting the downward movements of the cleaning strip in 0pposition to said springs.

3. In an apparatus of the character described, the combination in a window cleanto be moved away from the pane during its upward travel when said strip is in proximity to its uppermost position.

Signed at Seattle, Washington, this 8th day of June, 1918.
